In the above case, if it is acceptable to keep the display, the display is continued in step S111. If it is desired to change the zoom area display during the continuous display, step S7
And the zoom position is designated again to the keys 1 to 9.

[Embodiment 2] The outline of the configuration of a DVD player according to another embodiment of the present invention will be described.

Since [Embodiment 2] has many parts in common with [Embodiment 1] described with reference to FIGS. 1 to 4, different parts will be mainly described with reference to the flowchart of FIG. .

In the flowchart shown in FIG. 5, the start power is turned on, and steps S11, S12, and S12 are performed.
FIG. 13 is a flow chart shown in FIG.
1) Start power ON, step S1, step S2,
It is the same as step S3.

In this [Embodiment 2], step S13 is executed.
When the user presses the zoom key of the remote controller R, the CPU unit enters the double standby mode in step S31, and recognizes the keys 1 to 9 pressed thereafter as the keys dedicated to the zoom function.

In order for the user to know that the zoom standby mode has been entered, the video data processing section 6 reads out the full-scale cursor graphic data from the memory section 8 and displays the full-size cursor.
At this time, character information such as "2x zoom standby" is displayed in order to know how many times to zoom up.

Next, when it is desired to change the double standby mode, if the zoom key of the remote controller R is pressed again in step S32, the CPU enters the triple standby mode in step S31. 9 are recognized as keys dedicated to the zoom function, the same state as in the case of the double magnification is displayed, and character information such as "3x zoom standby" is displayed.

To cancel the triple standby mode, if the zoom key is pressed again in step S34, the standby is released and the process returns to step S12.

In step S15, an image portion to be zoomed in is selected from the full size cursors C1 and C2 at the lower and right ends of the screen and the whole image, and any one of the keys 1 to 9 is selected and pressed. The correspondence between the keys 1 to 9 and the image portion is the same as in [Embodiment 1].

The following steps S17 to S19
Are the same as steps S7 to S111 in [Embodiment 1]. Steps S81 to S85 and steps S101 to S105 are the same.

This [Embodiment 2] is similar to [Embodiment 2].
Compared with [1], at the moment when the user wants to zoom in while watching the entire moving image, the user can select a desired area by one action of the keys 1 to 9, which is convenient.

[Embodiment 3] An outline of the configuration of a DVD player according to still another embodiment of the present invention will be described. [Embodiment 3] also has many parts in common with [Embodiment 1] described with reference to FIGS. 1 to 4, and therefore, the following description will be made with reference to the flowchart of FIG.

In the flowchart shown in FIG. 6, the start power ON, steps S21 and S22 are the same as the start power ON, step S1 and step S2 of [Embodiment 1] in the flowchart shown in FIG.

In the present [Embodiment 3], the zoom key is not used, an image portion to be zoomed in is selected from the whole image in S23, and one of the keys 1 to 9 is immediately selected and pressed, and in S24, the video is The zoom function of the data processing unit 5 is operated. The correspondence between the keys 1 to 9 and the image portion is the same as in [Embodiment 1]. From step S25 to step S26,
This is almost the same as the double zoom display from step S7 to step S9 in [Embodiment 1].

Next, in step S27, double zoom display is confirmed, and continuous display is performed as it is in step S30.

If it is desired to change the double zoom display, the numeric key corresponding to the area where the cursor is zoomed is pressed again in step S28. In step S29, the zoom is tripled. If there is no problem, display continuously. The change of the magnification, the change of the zoom area, and the release of the zoom are performed in the same procedure using the same numeric keypad instead of the zoom key, and the description thereof will not be repeated.

This [Embodiment 3] is described in [Embodiment 3].
As compared with [1] and [Embodiment 2], a zoom image can be displayed faster without using a zoom key.

However, during a normal reproduction operation, there is a restriction that a ten-key pressed in a tight manner cannot be used for other than the zoom function. For example, as a method for selecting a chapter, the step of [5] [ENTER] to move to chapter 5 cannot be used. The user must press the numeric keypad after entering another chapter selection mode.
In a specific case, a [CHAPTER] key is provided and [C
It can be easily realized by pressing [HAPTER], [5], and [ENTER].

In the above embodiments, the case where each key of the remote controller R is operated has been described. However, the control key 7 having the same function of the DVD player may be used. Use
Even if both zoom keys and numeric keys are freely selected and used, the same function can be exhibited.

The above-described embodiment is merely an example, and many modifications are conceivable. The magnification and zoom enlargement procedure can be freely changed by a preset system program.

[Embodiment 4] Finally, [Embodiment 1] [Embodiment 2] or [Embodiment 3]
In the following, an example of a change procedure for displaying a zoom image in another zoom region while displaying a zoom image in a certain zoom region will be described.

As described above, when changing the zoom area, data of the desired zoom area is read and processed by designating the desired zoom area by using the cursor key or numeric keypad as a zoom position designating key. A double or triple zoom image is displayed.

In this [Embodiment 4], when the zoom area is changed, a desired zoom image is not directly displayed, but an area connecting the area before the change instruction and the area instructed to change. Is configured to display the desired zoom image after the zoom image is displayed.

This will be described below with reference to FIGS. 3D, 4, 5 and 6. Here, as an example, when the zoom image of the zoom area of the screen 11 in FIG. 3D is displayed at the time of 3 × zoom, the zoom image of the zoom area is changed to the zoom area of the screen 19 upon receiving a change instruction. Will be described.

[Embodiment 1] In [Embodiment 2] or [Embodiment 3], S111 in FIG.
When an instruction is given to display a zoom image in the zoom area of the screen 19 while displaying a zoom image in the zoom area of the screen 11 in S19 of FIG. In S15 or S23 in FIG. 6,
The data of the zoom area on the screen 19 is simply read, processed, and a zoom image is displayed (S8 in FIG. 4, S16 in FIG. 5).
Alternatively, S25 in FIG. 6).

On the other hand, in the present [Embodiment 4],
Read and process the data in the zoom area on screen 19,
Step of displaying a zoom image (S8 in FIG. 4, S2 in FIG. 5)
Before step 16 or S25 in FIG. 6, another step is added. In this separate step, the position of the screen (screen 11) before the change instruction and the screen (screen 19) instructed to change
A preferred screen to be displayed in the change process, that is, the position of the screen (screen 15) connecting the screen 11 and the screen 19 is calculated from the relationship with the position of the screen 11 and the zoom image of the screen is displayed. It should be noted that the calculation of the position of the screen that is preferable to be displayed in the change process is calculated by the CPU 4,
The zoom image may be generated by the data processing unit 5. Further, the CPU 4 may have in advance a correspondence table between the screen before the change instruction and the screen for which the change instruction is made and the screens connecting them, as a table.

FIG. 8 shows the correspondence between these screens. As is clear from this figure, for example, when changing the zoom area from the screen 11 to the screen 13, the zoom image of the screen 12 may be displayed first, and then the zoom image of the screen 13 may be displayed. When the zoom area is changed to 17, the zoom image of the screen 14 may be displayed first, and then the zoom image of the screen 17 may be displayed.

FIG. 9 shows the correspondence between screens when the zoom region is further subdivided. Screen 91 to Screen 912
When the zoom area is changed, the screen 92 located near the line connecting the position of the screen 91 and the position of the screen 912,
The zoom image of the screen 912 may be displayed after the zoom image of the screen 95 or 96 is displayed. The concept is the same even when a part of the zoom region overlaps each other as shown in FIG.

According to the present [Embodiment 4], when the zoom area is changed, instead of displaying the zoom image of the change destination directly, the zoom image of the change process is displayed and then the zoom image of the change destination is displayed. Therefore, it is possible to change the zoom region as if the user naturally moved his / her eyes, and to provide a zoom function that does not make the user feel uncomfortable or confused.

Lastly, another example of a change procedure when displaying a zoom image in a certain zoom region while displaying a zoom image in another zoom region will be described. Here, as an example, the zoom image of the zoom area is changed to the zoom area of the screen 19 in response to a change instruction when the zoom image of the zoom area of the screen 11 in FIG. Will be described.

In this example, when displaying the changed zoom image, the zoom images of all the zoom regions are displayed once starting from the zoom region before the change, and then the changed zoom image is displayed. .

Also in this example, another step is performed before the step of reading and processing data in the zoom area on the screen 19 and displaying the zoomed image (S8 in FIG. 4, S16 in FIG. 5, or S25 in FIG. 6). Add. In this separate step,
When the change is instructed, the zoom image is displayed as a whole. That is, the zoom images of the corresponding screens are sequentially displayed so as to make a round in the clockwise direction starting from the position of the screen 11. That is, as shown in FIG. 10, the screen 12, the screen 13, the screen 16, the screen 1
9, the screen 18, the screen 17, the screen 14, and the screen 15 are all displayed in one order, and then the zoom image of the screen (the screen 19) for which the change was last instructed is displayed. The control for displaying the images sequentially clockwise is performed by the CPU.
4 and the data processing unit 5 may generate the zoom image.

In this example, the zoom images are sequentially displayed clockwise starting from the screen before the change.
It goes without saying that it may be counterclockwise.

According to the present embodiment, the zoom image whose change has been instructed is displayed after displaying all the zoom images as a whole, so that the user does not have to perform the operation of displaying all the zoom images one by one. The user can recognize the zoom image to be displayed on the screen, and the usability is improved.

[0084]

As described above in detail, according to the structure of the present invention, the operation burden on the user is small, and the position of the enlarged zoom screen on the screen and the zoom magnification are clear. Certain video display devices can be provided.
